The general rule of thumb I've always used is .080 (2mm) on the intake side and .100 (2.5mm) on the exhaust side. This is used on pushrod motors that in general use bigger clearances, so you may be able to run tighter tolerances than that, but DO NOT build your motor on that assumption. The best thing you can do is to contact your local cylinder head guy and ask him given your valve train layout and cam specs how tight you can run that tolerance.
I wish they made cams for my M104 that didn't cost as much as my entire car did....
